Figure 12: Uptake of doxorubicin loaded MPTL by MCF-7 cells, the cells are incubated with drug loaded nanostructures for about 75 min, a-c: with permanent magnetic field (MF), d-f: without (MF) and irradiated with Ar laser at 37°C. The images are obtained by the fluorescence microscope equipped with green and red filters for, Annexin V-FITC and DOX respectively (n=3).
